ScienceIg Nobel Prizes showcase surprising science

The satirical Ig Nobel Prizes, which celebrate science’s quirky side, were held outside the US for the first time this year because of travel concerns. Researchers in costumes collected awards from Nobel laureates for studies involving cockroaches worn on heads, nose-blowing, kissing cavemen and buried underwear. Paul Piff’s social psychology team won for research linking wealth to greater self-interest and entitlement.
